NASA has called a press conference to ‘discuss new results about ocean worlds.’

The US space agency says the new findings come from both the agency’s Cassini spacecraft and the Hubble Space Telescope.

‘These new discoveries will help inform future ocean world exploration – including NASA’s upcoming Europa Clipper mission planned for launch in the 2020s – and the broader search for life beyond Earth,’ NASA said.

It will reveal the finding at 2pm on Thursday – but refused to give any more clues.

The event, to be held at the James Webb Auditorium at NASA Headquarters in Washington, will include remote participation from experts across the country.

The include several members of the Cassini team, raising speculation the announcement could be a revelation about Jupiter’s sixth-closest moon Europa, ahead of the 2020 Europa Clipper mission, or Enceladus, the sixth-largest moon of Saturn.
